The truth of the water purifier, don’t be fooled!

If you really analyze the water purifier from the principle of environmental protection, you can write it from the waterworks to the end of the water purifier, but the article will become long and smelly, so simply ask everyone’s concerns and some of the industry. The tricky is simplified in the form of a question and answer.

What is the water purifier? How to classify?
A water purifier is a device that converts “not clean water” into “relatively clean water”, and the classification can be divided by its filtration level. The most commonly used on the market are ultrafiltration water purifiers and reverse osmosis water purifiers, in addition to water softeners.

Main use: Effectively filter out harmful substances such as sediment, rust, bacteria, colloids, macromolecular organic substances in water, and retain minerals and trace elements beneficial to the human body.

Advantages: Completely remove bacteria and algae including some viruses, and can safely drink where the metal ion content is low (although it is not recommended to drink directly).

Disadvantages: It is impossible to filter out calcium and magnesium ions and heavy metals, and there is also scale.

Usage: The filter cartridge is replaced regularly, and the replacement cycle of different filter cartridges is slightly different.

Main use: By using the ion exchange principle, the calcium and magnesium ions in the water are replaced by Na+ in the sodium salt in the machine. Thereby obtaining soft water.

Advantages: The water stains splashed by soft water are no longer obvious, the clothes are not easy to be stiff, the faint yellowing, the water heaters and other pipes are not easy to block, the bathing skin is not dry, and the shampoo is not dry and knotted and easy to comb. Generally, the water quality in the south is good and the north is poor. If the hard water tastes bitter, it is better to pack it.

Usage: Periodically replace the filter element (the salt inside), the replacement cycle of different filter elements is slightly different.

What is a reverse osmosis water purifier (RO machine)?

In general, the RO machine has five layers of filters.

Advantages: Currently the best products in the market.

Disadvantages: Waste water is produced, and a cup of pure water is produced with one or more “waste water”.

What is a pre-filter?


Main use: Installed behind the water meter to filter sediment, rust and large particulate matter in tap water, prevent a large amount of sediment impurities in the water net from causing harm to the human body, and pre-protect the water-using appliances.

Advantages: no special after-sales service, no need to replace the filter element, the filter effect is intuitive and transparent (the filter effect and use state can be clearly observed), and the service life is long (up to several decades).

Disadvantages: only coarse filtering.

Usage: After the tap water main road, observe the dirt deposition in the lower part regularly. When there is more dirt, open the lower valve and automatically flush out the dirt.

Is it necessary to install a pre-filter?

Generally, the water quality of the households is poor (with sediment, rust, and large particles). In the few months after the new home is in place, the water from the faucet is getting smaller and smaller. If you remove it, you can see such a situation. You can consider installing it. .

How to reserve a location?

Here is a relatively standard connection. If someone at home will change the water pipe (in fact, it is quite simple), you don’t have to reserve a backup waterway to deal with the emergency. If the water filter is removed, connect it with a stainless steel hose or braided tube.
When do you want to change the filter?

When the water consumption is too large, the filter element should be replaced in advance according to the water consumption. Signs when replacing the household water purifier filter

First, the water is too slow: the pre-filter or filter is clogged.
Second, the taste is not good: the service life of the rear activated carbon filter has arrived.

How to choose the water purifier that suits you?

If the water source has large particles such as sand, be sure to install a pre-filter to protect the waterway hardware and water appliances in the home. Xingge suggested that the general family can install, it is inevitable that one day the community water tank cleaning can still be a little protective, installed with a backwash function, can be used repeatedly, the service life can reach more than 10 years, the price is quite high, see When the color is dirty, clean it up and continue to use it.

If it is a heavy industry polluting city, choose RO water purifier to filter out heavy metal ion insurance.

If there is a lot of scale in boiling water (generally the water quality in the north is hard), or the pursuit of drinking water is relatively high, you can choose RO water purifier.

In areas with softer water quality (generally in the south), if you want to save money, you can use ultrafiltration.

Is the water in the waterworks really dirty?

Water plants use much better equipment than household water purifiers, and water plants in each region (for local unique pollutants such as heavy metals) will have different measures to deal with. The factory indicators also have national standard monitoring. (I didn’t contact the author, so I can’t reprint the original text. For details, please refer to the user: Lele Xiaoyi. Answer to the question “Our tap water is really dirty?”

Why is there a problem with the tap water coming out?

Generally, heavy metal pollution, pipe network pollution, secondary pollution, residual chlorine and other issues are the key to affecting users’ water use. Most of the reasons are in the water tanks for transportation and community living water!

The residual chlorine is so terrible, what if I don’t have the money to install the water purifier?

What you are afraid of is the carcinogen chloroform (chloroform), but it requires a high concentration of chlorine gas and special equipment to generate, and the reaction process can easily become carbon tetrachloride. The residual chlorine content of the water plant is 0.05~4mg/L. Do not have the conditions for the formation, and the low content after boiling is poor, don’t worry.

Call on those brainwashed dealers and salespeople to stop using their ridiculous reasons to market their water purifiers.

Do drinking regular water often make people lack minerals?

It does take away some of the minerals, but it is smaller than the daily food and mineral intake. You can rest assured that it is important to use pure water to wash the milk.

Is the pipeline machine useful?

The water coming out of the water purifier is clean enough. The pipeline machine is to ensure that there is no secondary pollution in the middle to directly boil water. The key to the purchase depends on the internal sealing degree.

But the bacteria floating in the air are more fragile, boiling the water, and these weak bacteria will die.

So buying or not buying is all right.

Does RO produce more wastewater? Will it be wasted?

First of all, these waste waters are not dirty water, washing clothes, washing the bathroom, taking a bath, etc., no problem at all.

Most of the “waste water” outlets of the RO machine are pressure drainage (even if there is no water in the clean water), my family will drain the drainage pipe to the water tank of the bathroom. The connection is as follows.

Which water purifiers need electricity?

General RO machines and water softeners need electricity.
The ultrafiltration machine can work with water pressure and does not need electricity.
Front water filter does not require electricity
In any case, a place where the water purifier is prepared (general kitchen sink) can be reserved for a socket.
